ENTER TOTAL STANDBY CURRENT (Sum of column):
ENTER TOTAL ALARM CURRENT (Sum of column):
* Typical currents only. Refer to specific product information sheets.
Calculations:
REFERRING TO TABLE A-2, ENTER STANDBY TIME REQUIRED (in hours): ______
REFERRING TO TABLE A-2, ENTER ALARM TIME REQUIRED (in minutes): ______
CONVERT ALARM TIME REQUIRED TO HOURS (using formula below):
(minutes)/60 = ______hours
CALCULATE TOTAL AMPERE HOURS (using formula below):
((TOTAL STANDBY CURRENT) x (STANDBY TIME REQUIRED in hours)) + ((TOTAL ALARM CURRENT
x ALARM TIME REQUIRED in hours)) = ______TOTAL AMPERE HOURS
CALCULATE BATTERY CAPACITY WITH A DE-RATING FACTOR OF 20%
(using formula below):
1.2 x TOTAL AMPERE HOURS = ______BATTERY CAPACITY
REFERRING TO TABLES A-3 AND A-4, DETERMINE NUMBER OF POWER SUPPLIES NEEDED:
NOTE: If TOTAL ALARM CURRENT > 5.4 A, then 2 or more PSUs are required.
